Molecular analysis of abnormal hemoglobins in beta chain in Aegean region of Turkey and first reports of hemoglobin Andrew-Minneapolis and Hb Hinsdale from Turkey.

AbstractOBJECTIVES:
The Agean is one of the regions in Turkey where thalassemias and abnormal hemoglobins (Hbs) are prevalent. Combined heterozygosity of thalassemia mutations with a variety of structural Hb variants lead to an extremely wide spectrum of clinical and hematological phenotypes which is of importance for prenatal diagnosis.
METHODS:
One hundred and seventeen patients and carriers diagnosed by hemoglobin electrophoresis (HPLC), at risk for abnormal hemoglobinopathies were screened for mutational analysis of the beta-globin gene. The full coding the 5' UTR, and the 3' UTR sequences of beta-globin gene (GenBank accession no. U01317) were amplified and sequenced.
RESULTS:
In this study, a total of 118 (12.24%) structural Hb variant alleles were identified in 1341 mutated beta-chain alleles in Medical Genetics Department of Ege University between January 2006 and November 2013.
DISCUSSION:
Here, we report the mutation spectrum of abnormal Hbs associated with the beta-globin gene in Aegean region of Turkey.
CONCLUSION:
In the present study, the Hb Hinsdale and Hb Andrew-Minneapolis variants are demonstrated for the first time in the Turkish population.
